To all whom "it may concern:

Be it known that I, OLIVER S. GANDY,0f Newport, in the county ofCumberland and State of New Jersey, have invented certain new and usefulImprovements in Cultivators;- and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which'it pertains to make and useit, reference being had to the accompanying drawing, which forms part ofthis specification.

My invention relates to an improvement in cultivators; and it consistsin the arrangement and combination of parts that will be more fullydescribed hereinafter, whereby the standard is braced in position.

Figures 1 and 2 are side elevations of my invention in slightlydifferent forms.

(1, represents the beam, and b the standard, pivoted thereto in theusual manner. Upon the lower end of this standard is fastened, in anysuitable manner, the shovel, which shovel consists of a removable steelpoint, 0, and a mold-board, cl. When this point is worn out it can bereadily removed and replaced by another without having to throw away themoldboard, as is the case when the two are made in a single piece. I

Secured to the lower end of this standard, and extending upward throughthe guide 9 on the rear end of the beam, is the curved brace h, whichserves to brace and hold the standaid at any desired angle. Passingthrough the guide 9 is the set-screw '5, which clamps the brace rigidlyto the side of the beam, and thus prevents it from moving after it hasonce been adjusted. Where an iron beam is used the upper end of thestandard will be hollowed out as shown, so as to pass up over each sideof the beam, which beam will be preferably made thicker at this pointwhenever the upper end of the standard will come in contact with it.Inthe lower edge of the slide 1 is made a notch, which catches over thetop of the recess made in the top of the standard, so as to bind theslide and the standard securely together. As thus fastened together, theslide will be brought up under the lower side of the beam, as shown, andwill bear against it as it moves back and forth with the standard. Beingthus secured to the standard, as the standard has its lower end adjustedback and forward in order to cause the shovel to run shallow or deep,the rear end of the slide will move back and forth in the guide-frame n,which is secured to the under side of the rear end of the beam at. Therear end of this slide is somewhat enlarged, as shown, and passingthrough the rear end of this guide-frame, so as to bear against thisenlarged head, is the set-screw 7', which is so adjusted as to preventany backward movement on the part of the frame, after it has once beenadjusted in position. Also, passing up through the under side of theguide-frame is another set-screw, s, which clamps against the under sideof the slide, and thus still further assists in holding the slide in theposition into which it may be adjusted.

Thus it will be seen that the standard is held at any desiredinclination by means of the set-screw, which clamps the side of thecurved brace, and by means of the two setscrews 4 s, which hold theslide securely in place. Should the screw which holds the curved bracebe insufficient, then the other two screws will answer to hold the beamin position.

Where a wooden beam is used, as shown in Fig. 2, the upper end of thestandard will pass through the beam, as shown, and the slide 25 will beplaced upon the top of the beam, and held in position by means of theset-screw c, which passes down through the iron frame M, which straddlesover the top of the beam and the slide. As the standard is adjusted backand forth, the slide and the curved brace will be adjusted with it, andafter the slide and the curved brace have been securely locked inposition, the standard will be held in the position to which it isadjusted, beyond all danger of its working loose.

The oval casting or fender x that rests upon the bottom of the beam, andthrough which the upper part of the standard passes, causes the standardto have a bearing against the beam when the standard is placed at anyangle, and takes the strain from the bolt that passes through the sideof the beam and the upper end of the standard. v

The large screw y, that passes down through the beam to the under side,screws into the casting and through it, so as to bear against theshoulder on top of the rear part of the standard, and for the purpose ofholding it at any angle desired. This screw, with the curved brace,holds the standard immovable. The great trouble of using the brace aloneis that the set-screw is so apt to work loose, and as it works loose thestandard will be constantly changing its angle, so that no dependencecan be placed upon it; and it is for this reason that I have added theslide, in connection with the curved brace, for the purpose of holdingthe standard at any desired angle.

Having thus described my invention, I
